Free body diagram (centripetal force)

simple question really - how do you draw the free body diagram for a car going around a corner?

2. Relevant equations

n/a

3. The attempt at a solution

i know the net force, the centripetal force, points towards the middle. i have an engine force pointing tangentally outwards...where is the missing force? is it friction? and when i try to figure out its direction i have it pointing between the engine force and centripetal force but that doesnt make sense if its friction.

Engine force usually isn't needed, but it's direction would be to accelerate the car forward.

How about forces in the vertical direction?

forces vertically would be weight and normal i think.

im trying to draw my diagram from a birds eye view. and i cant figure out which way friction would point or if there is another force too. my logic is that if there is a forward force (engine force?) there would have to be at least one other force such taht those vectors add up to the centripetal force (which is perpendicular to the engine force and points towards the center of the circle).
